Lantana camara plant named ‘UF-T3’

ABSTRACT

A new and distinct cultivar of  Lantana camara  plant named ‘UF-T3’, characterized by its moderate vigor, mounding growth habit, free flowering, bright yellow/orange flower color, little fruiting, high level of female sterility, high level of male sterility, and lack of hybridization with  Lantana depressa , is disclosed.

Latin name of the genus and species of the plant claimed: Lantana camaraL. (Lantana strigocamara R. W. Sanders).

Variety denomination: ‘UF-T3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lantana,botanically known as Lantana camara, and hereinafter referred to by thename ‘UF-T3’.

Lantana camara is a member of Verbenaceae. Plants of this speciesattract numerous species of butterflies, tolerate harsh environmentalconditions, have low maintenance requirements, and are easy to grow,making L. camara highly desirable for use in containers, hangingbaskets, and landscapes. Commercial production of L. camara iswidespread in the nursery industry, especially in the southern UnitedStates. However, this species has escaped cultivation through seeddispersal and has hybridized (as pollen donors) with Lantana depressa, arare species native to Florida, resulting in its classification as aCategory I invasive species for South and Central Florida. Very few ofthe existing commercial L. camara cultivars are highly male- andfemale-sterile. Therefore, there has been a strong need for new sterilecultivars in L. camara.

‘UF-T3’ is a product of a planned breeding program at the University ofFlorida. The primary objective of the breeding program is to create newsterile Lantana cultivars with attractive plant growth habits (mounding,semi-mounding, to spreading), freely-flowering, and attractive flowercoloration.

The new Lantana originates from a planned cross between ‘Dallas Red’(unpatented) and a proprietary breeding line LAOP-9. ‘Dallas Red’ wasselected as the female parent for its tetraploidy level, bright redflower color, and lack of production of unreduced female gametes.Breeding line LAOP-9 was selected out of a population of progeny fromopen pollinated ‘Lola’ (unpatented) in Wimauma, Fla. It was used as themale parent in the stated cross for its diploidy level, compact growthhabit, and lack of production of unreduced female gametes. The statedcross was made in April 2007 in Wimauma, Fla. ‘UF-T3’ was discovered andselected in Wimauma, Fla. in October 2008 as one flowering plant withinthe progeny of the stated cross.

Asexual propagation of the new Lantana by vegetative cuttings in acontrolled environment in Wimauma, Fla. since 2008 has shown that theunique features of this new Lantana are stable and reproduce true totype in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar ‘UF-T3’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature andlight intensity without any change in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘UF-T3’. These characteristics incombination distinguish ‘UF-T3’ as a new and distinct cultivar ofLantana: 1) Moderate plant vigor; 2) Mounding and outwardly spreadinggrowth habit; 3) Dense dark-green-colored leaves; 4) Freely floweringhabit; 5) Yellow and orange-colored flowers that are held above andbeyond the foliage; 6) Little fruiting and no or few berries; 7) Highlevel of female sterility; 8) High level of male sterility; and 9)Little hybridization potential with Lantana depressa.

Plants of the new cultivar differ from plants of the female parent, thecultivar Dallas Red, in the following characteristics: 1) Plants of thenew cultivar are triploids, while plants of ‘Dallas Red’ aretetraploids; 2) Plants of the new cultivar are mounding and outwardlyspreading, while plants of ‘Dallas Red’ are more upright and erratic; 3)Flowers of the new cultivar are yellow-colored when initially open andturn orange when matured, while flowers of ‘Dallas Red’ are red-colored;4) Plants of the new cultivar produce no or few fruit and are highlyfemale-sterile, while plants of ‘Dallas Red’ are female-fertile andproduce more fruit; and 5) Plants of the new cultivar have low pollenstainability or viability, while plants of ‘Dallas Red’ have much higherpollen stainability or viability.

Plants of the new cultivar differ from plants of the male parent, thebreeding line LAOP-9, in the following characteristics: 1) Plants of thenew cultivar are triploids, while plants of LAOP-9 are diploids; 2)Plants of the new cultivar are mounding and outwardly spreading, whileplants of LAOP-9 are more upright; 3) Flowers of the new cultivar areyellow-colored when initially open and turn orange when matured, whileflowers of LAOP-9 are yellow-colored; 4) Plants of the new cultivarproduce no or few fruit and are highly female-sterile, while plants ofLAOP-9 are female-fertile and produce more fruit; and 5) Plants of thenew cultivar have low pollen stainability or viability, while plants ofLAOP-9 have much higher pollen stainability or viability.

DETAILED BOTANICAL DESCRIPTION

In the phenotypic description, color references are made to The RoyalHorticultural Society Colour Chart (1986 Edition) except where generalterms of ordinary dictionary significance are used. Plants used for thedescription were grown in the summer of 2011 in Wimauma, Fla. for 3months from when terminal cuttings were made. Plants were planted in a10.2-cm container and only trimmed minimally as needed at this time.Plants were grown outdoors for 3 weeks in early September in Wimauma,Fla. before flower color descriptions was done. During the production ofthe plants in the polypropylene-covered shadehouse, temperatures rangedfrom about 20.5° C. to about 36.1° C.

ASSESSMENT OF FEMALE FERTILITY

Four experiments were conducted simultaneously at the Indian RiverResearch and Education Center (IRREC) in Ft. Pierce, Fla. (southeastFlorida, USDA hardiness zone 10, and AHS heat zone 9-10), at the GCRECin Balm, Fla. (southwest Florida, USDA hardiness zone 9A, and AHS heatzone 10), at the Plant Science Research and Education Unit (PSREU) inCitra, Fla. (northern Florida, USDA hardiness zone 8B, and AHS heat zone10), and at the North Florida Research and Education Center (NFREC) inQuincy, Fla. (northern Florida, USDA hardiness zone 8B, and AHS heatzone 9). The four experiment sites are located in three differenthardiness zones (10, 9A, and 8B) and two different heat zones (10 and 9)(American Horticultural Society, 1998; National Gardening Association,2011). The experimental design used in Ft. Pierce and Balm was arandomized complete block with three blocks. The distance between fieldblocks were at least 50 feet. Each plot within the block at these twosites consisted of two plants for each cultivar and one L. depressaplant (mixed planting of triploids and native Lantana). The spacingbetween plants within each plot was 6 feet. The same experimental designand the same number of blocks were used in Quincy and Citra, except thatL. depressa plants were not installed between triploid plants (pureplanting of triploid plants). L. depressa does not occur naturally innorth Florida. At each experimental site, ‘Pink Caprice’ was included asa control. It is commercially produced and very prolific in fruit (andseed) production. ‘Pink Caprice’ was planted at least 150 feet away from‘UF-T3’.

Every four weeks beginning on late July 2009 until mid-December 2009, 20peduncles (flower or fruit clusters) were harvested randomly from eachof the plants grown at the four experimental sites (refer to the above)and berries on each peduncle were counted. A total of six harvests weremade for each plant at each experimental site. Thus 120 peduncles wereexamined for each Lantana cultivar in each experimental plot during agiven harvest and 2,880 peduncles were examined across the fourexperimental sites through six harvests (20 peduncles per plant×2 plantswithin a block×3 blocks×4 sites×6 harvests) for each cultivar. Ananalysis of variance was conducted using the general linear modelprovided in SAS (PROC GLM; SAS Institute 2011) to compare the fruitproduction of ‘UF-T3’ with that of ‘Pink Caprice’.

‘Pink Caprice’ produced many more berries. Each peduncle of ‘PinkCaprice’ bore an average of 1.143 to 22.838 berries, with an overallaverage of 10.451 across the four sites and six harvests. The number ofberries per peduncle on ‘Pink Caprice’ grown in Balm and Ft. Pierceranged from 1.143 to 12.416, averaged to 6.783, while the number ofberries per peduncle on plants grown in Quincy and Citra was 7.150 to22.838, averaged to 14.118, more than 1-fold greater.

The number of berries ‘UF-T3’ produced per peduncle ranged from 0 to0.074 and averaged to 0.019 across four experimental sites and over 6months (Table 1). This level of fruit production represents greater than99% reduction from the fruit production capacity of ‘Pink Caprice's’.‘UF-T3’ showed similarly low levels of fruit production regardless ofwhether they were planted purely (without L. depressa in Quincy andCitra) or interplanted with L. depressa (in Balm and Ft. Pierce).

Mature berries were collected from each plant in the above describedexperiments. Seeds were extracted, cleaned, and air-dried. Seeds weregerminated in a 10.9-cm×10.9-cm transparent polystyrene germinationboxes (Anchor Paper Company, St. Paul, Minn.) containing 2 sheets ofgermination paper (Anchor Paper Company) moistened with 15 mL ofnanopure water. Germination boxes were placed in temperature andlight-controlled chambers equipped with cool-white fluorescent lamps(Model 818; Precision Scientific, Winchester, Va.). The germinationcondition was 12 hours light at 25° C. (photosynthetic photon flux was22 to 30 μmol m⁻²s⁻¹ at shelf level) followed by 12 hours dark at 15° C.Germination of seeds was monitored every other day for a period of 60days. An additional 5-10 mL of nanopure water was added to thegermination boxes as needed. A seed was considered germinated whenradicle emergence was 2.0 mm or greater. Seeds were removed oncegermination occurred to prevent inaccurate data collection.

‘Pink Caprice’ seeds germinated readily, with an average germinationpercentage of 63.3 (Table 2). The number of seeds collected from eachexperimental site (six plants) over 6 months for ‘UF-T3’ ranged from 0to 13 (Table 2). The germination percentage of these seeds was between15.4 and 50.0, averaged to 24.4 (Table 2).

Fruit (seed) production per peduncle and seed germination are theprimary factors determining Lantana's female fertility (or sterility).These two characteristics are factored into a female fertility index(FFI) by multiplying fruit production per peduncle and seed germination.The FFI for ‘UF-T3’ was 0.005 (Table 2), less than 0.1% of the ‘PinkCaprice's’ FFI (6.615), indicating an extremely high level of femalesterility in ‘UF-T3’.

ASSESSMENT OF POLLEN STAINABILITY

Pollen stainability is a good indicator of Lantana's male fertility (orsterility) and hybridization potential with Lantana depressa. Threepollen staining experiments were conducted using fresh anthers collectedfrom the plants grown in Wimauma, Fla. on 24 September and again on 16Nov. 2009 and from the plants grown in Ft. Pierce on 6 Oct. 2009. Ineach staining experiment, three inflorescences were collected per plantand three to four anthers were isolated from each of the inflorescences,resulting in eight to 12 anthers from any given plant and 48 to 72anthers for each lantana cultivar (two plants per replicate and threereplicates in each location). Collected anthers were placed in ˜100 μLof cotton blue solution (Eng Scientific, Inc. Product No. 6730, Clifton,N.J.) in a 1.5-mL Eppendorf tube and stained overnight at 65° C. Stainedanthers were rinsed three times with deionized water, placed onto amicroscope slide, squashed in a drop of 80% glycerol, and covered with acover slip. Pollen grains were observed under 400× magnification on aBH-2 microscope (Olympus, Tokyo, Japan). Well developed, full and deeplystained pollen grains were counted as stainable, while non-stained,partially stained, or abnormally-shaped pollen grains were counted asnon-stainable (aborted). The number of pollen grains examined for eachLantana cultivar in each staining experiment was between 1,752 and5,141. An analysis of variance was conducted using the general linearmodel provided in SAS (PROC GLM; SAS Institute 2011) to compare thepollen stainability of ‘UF-T3’ and ‘Pink Caprice’. The average pollenstainability of ‘UF-T3’ was 5.1% (Table 3). The average pollenstainability of ‘Pink Caprice’ was 65.6% (Table 3). These resultsindicate that the pollen stainability (or male fertility) of ‘UF-T3’ hasbeen reduced by 92.2% from that of ‘Pink Caprice’.

ASSESSMENT OF HYBRIDIZATION POTENTIAL WITH Lantana depressa

Two hand pollination experiments were performed in the greenhouse inWimauma, Fla., one in fall 2009 and one in spring 2010, to assess theability of ‘UF-T3’ to cause fruit set on L. depressa flowers. Stockplants were grown in #1 plastic containers filled with a commercialsoilless mix amended with a controlled release fertilizer (Osmocote,15N-3.9P-10K, 8-9 months release at 21° C.) at 7.12 kg·m⁻³. Temperaturesinside the greenhouse ranged from a low of 16° C. at night to a high of29° C. during day. No supplemental lighting was provided. Plants weredrip-irrigated, twice a week as needed. Fresh anthers were collectedfrom mature unopened flowers of ‘UF-T3’ and applied immediately toemasculated L. depressa flowers.

‘UF-T3’ effected 2.8% fruit set in the first hand-pollination experimentbut no fruit set in the second pollination experiment. Two seeds wereobtained but they did not germinate (Table 4). ‘Pink Caprice’ effectedan average of 8.9% fruit set. Seeds from L. depressa×‘Pink Caprice’ had65% germination.
